The really nice thing about Dinan for you is that it won't affect your warranty at all. It will cost you a little money, though. They do have high quality products.
The work that Dinan does is superb for the M cars (especially the E39 M5). The M3 exhaust sounds so mean on the M3, as opposed to the exhaust made for other 3 models. I highly suggest Dinan for more than one reason:
1. Warranty concerns are eliminated
2. Quality is superb
3. They offer random 10%/20% discounts from time-to-time
4. The increases may be conservative, but I assure you that the research they have done is made specifically for BMW. They don't focus on the straight line performance from 0-60 as their primary selling goal as other companies do. "Performance is not a number on a sheet, it's a combination of tuning to a perfection."
Dinan is conviently located at some local dealers to make their package seem even more involved.
